Improvement in pumps



UNITED STATES PATENT OFFICE.

DAVID L. JAQUES, OF HUDSON, MICHIGAN.

IMPROVEM ENT IN PUM PS'.

Specification forming part of Letters Patent No. 59,030, dated October 23, 1866.

To all 'whom it may concern:

Be it known that I, DAVID L. JAQUEs, of Hudson, in the county of Lenawee and State of' Michigan, have invented a new and Improved Combined Suction and Force Pump; and I do hereby declare that thefollowing is a full and exactdescription thereof, reference being had to the accompanying drawings,

and to the letters of reference marked there- Figure] is a vertical section through the center. Fig. 2 is a longitudinal exterior' view of the plunger.

In the several figures similar characters refer to like parts.

A indicates a vertical semi-section of the whole structure.

a is the cylinder,.drilled out in the usual manner, having a suitable flange at the lower end, with holes t t, for bolts or screws to fasten it with. o is an enlargement at the upper end, of a bowl shape. D, at the right side, is suction-pipe insertion, and E, on left side, is the force-pipe.

C is a wooden plug driven into the lower end of cylinder a., to which suction-pipe D and suction-valve e are attached.

d is a hole bored in plug C longitudinally and at right angles, so as to intersect, in which hole is introduced the suction-pipe D, either at side or bottom, as may be desired.

Valve e may be attached to the plug by means of screws or nails, being a leather valve.

b is the main body of the plunger, to which two heads, P andQ, are attached, with leather packing D D placed between the heads P and Q and end of part b,'that of end S for suction, and end f for forcing the water up into pipe E as the plunger descends, head P being adj usted by means of screw r, and head Q with screw-pin the plunger b to be drilled out t0 receive said screw-pin x, having a screw cut therein.

O is a hole drilled clear through head Q and pin x, making an opening from thc interior of plunger b into reservoir o.

r is the priming or outlet valve, with head V, that plays in the vacuum not filled by screw-pin w, piston extending down through and resting on lifting-valve Z.

J is a mortise or opening near the lower end, S, in which valve l is adjusted.

The valve-seat or end of plunger is provided with two openings, a n, for the water to pass up into and around the plunger, of which section l is a cross vertical View.

T T is the opening for the water to pass out through when valve r is down.

The dotted pi pe-,lines D and E represent the pipe-connections withthe cylinder.

W is the piston-rod by which the plunger is supported, secured with pin-bolt s.

Fig. l represents the water running out of pipe E through space y y around the plunger, then into openings or holes t t, and around head V ofv valve r, to opening O, and up :into the reservoir o, and then flowing back into well or cistern, leaving the reservoir full. Thus the pipe E does not remain full of water above when the pump is not in operation, and yet the pump is always primed.

Force the plunger down and the water will raise or lift up both valves and r, letting the water into the plunger-chamber and pipe E. The lifting of valve l opens the passage from lower chamber or body of water, and valve r is brought in close contact to opening O, closing it up and preventing the water from passing.

The pressure of water while the plunger is in motion will keep valve r to its proper place, and when the action ceases it will settle or fall back, as indicated, and retain water -in the reservoir c.

Thus it will be noted that the device I have' set forth is for a double-actin g pump-to wit, suction and force-making it suitable for deep or shallow wells, and for cisterns out or in door, preventing freezing, as the pipe is always free of. water when not in use.

Having thus described my invention, what I claim, and desire to secure by Letters Patent,

y1. The plunger b, of any suitable length,

consisting of heads P and Q and leather pack-
